Uni T UT139S Multimeter Review & Tear Down

[@Brian-uq6jm]

I have the 139E, basically the same meter with a different display. Have owned for over a year, never let me down. Accidentally left it in ohms on mains at some point, no problems, nothing broke.

[@markharrisllb]

I thought I’d commented on this video, it looks like I said a word Google doesn’t like. Mine is much brighter than yours and did come with an English manual. I prefer my 139s over my 61e+ which doesn’t doesn’t even have temperature. I would definitely recommend the 139s over the 61e+, it even looks better and there’s only about £5 between them.

[@mdzacharias]

I have a 139C and like it a lot. It won't replace my Flukes, but I got it for 20.00 inc freight. Deal of the week.

[@aurthorthing7403]

I have the original version of 139C and it's my favorite. I've seen some snobs dis it for various reasons... mainly because it was damaged after they abused it. I couldn't disagree with them more. It's an awesome meter.

Best of luck on Friday buddy. I am not a very religious person, but I will say a prayer for you and a speedy recovery. Get well soon my friend. Have Fun, Joe

[@iandawkins2182]

Thinking of you Bro. Love, love , love the channel and what you do for us all. Be well, be happy and PEACE !

[@georgechambers3197]

`Uni T makes the best cheap meters yet. That one beats the heck out of that last meter reviewed. 😁 Good luck with the surgery, I know you are probably a little nervous out it. I'm sure all will be well in the next few days. Thanks for taking the time to post these videos while in such pain!

[@TheDigitalAura]

I think everybody is going to be comparing this to the UT61E and unfortunately 6000 Counts just doesn't cut it. A set of probemaster probes would fix the continuity speed without a doubt, probably the best probes in existence.

[@RomanKuechler]

As always very interesting. I personally was very dissapointed about the UT-71D and cannot imagine ever to buy a UNI-T device again... Best wishes for friday.

[@MuhammadKhanRetti]

Saw your review very well explained by you. Is 3.17 dollars I can find it online and I have ordered it is ok for this price I have no special use just a little bit of repair will it be ok for me and my english is not special to write I'm sorry if I made a mistake

[@elmakednos]

Does it meter Frequency and what is the maximum frequency that it reads?

[@rrowan327]

LOL Lets call it a Calibration card. Good Luck on Friday my Friend.

[@matheusgolz5361]

The 10A to COM PCB copper width was 4~5 mm, ok. But there is a plastic screw insert right in the middle of it, leaving a very small path in each side!!! I don't get it, why bother using a large PCB trace if you freak it up right in the midle? I have a 139C, but still don't trust UNI-T with mains voltages. Looking for good value/secure alternatives.

[@sylvainmartin73]

I heard you mention in another video that you like gold plated probes, got any suggestions on a set of probes you would recommend? I've got a couple of UNI-T meters as my daily drivers but the struggle is real when it comes to check continuity and getting good probe measurements

[@Sv3TL10]

Thanks for the great review, it was one of the reasons for me to choose this multimeter. You checked the impedance at loZ and and at normal V, can I ask, if you are still keeping this multimeter, can you tell me what readings dou you get on dc mv and on ac mv when you check the impedance. Mines readings are about 6Mohms at dc mv and about 4.4Mohms at ac mv, so I was wondering if it is normal? Especially for the ac mv :)

[@BogdanSerban]

I was just looking for a meter and BAM your video pops up in my feed

[@mikeoliver3254]

The trouble it had at the lowest resistance and capacitance range troubles me. It may make a nice automotive repair meter but I am not confident that it would be a great meter for a new hobbiest. But it might be fun to try to modify and it looks like you could change the firmware which may solve the issues it has. It definitely looks well built and safe to use. Great review Paul and good luck on Friday, I’ll be thinking of you man.

[@TheMightybum]

I have the exact same meter with a normal display UT139E. It seems like the low range issue he had was due to the shitty test leads. The meter functions fine for me.

[@pinterelectric]

Good luck my friend!

[@MalagasOnFire]

The uni-t 139A which is the basic has similar readings on voltages, better at low values on resistance ( its 2000 count meter ) but it came with crappy bad smelling leads aka even worse than this meter, and the screw on the battery compartiment is long, but has 2xAA batteries so you don't need to open that offen.

[@MCsCreations]

Pretty interesting meter, dude. 😊 Great luck Friday! Everything is going to work fine! 😊

[@whitehoose]

I do like uni-t kit, still plasticky .... but nicer placky than some - there's also a little give so while you can't drop it far, it doesn't disintegrate on impact. My leads came with a specially thick and totally insulating coating of factorium slime - I had to clean all the connectors and points with alcohol (surprisingly the case didn't dissolve). Now they don't do too badly. Mine is 210e with the contactless current clamp, but still as you say no real worries when testing domestic mains, which these days is as high as I go. I have a snazzy pacemaker installed and higher volts could theoretically trigger the ICD which isn't fun!! Like the Uni-T it's pocket sized and follows me everywhere (although I hope uni-t didn't build mine!!!). I've been visiting medics all week myself - so missed yours until today which is after the fact. Presumably you know how it went - so hope things are optimistic. I'm guessing the worst news would be being told you had to give up on oscilloscopes :D Stay safe ...

[@GeorgeJFW]

Great video man I have been very impressed with the UNI-T stuff I have picked up in the past.

[@michaelpadovani9566]

Another great meter review. Best of luck Friday brother

[@soundengineer6332]

Dioda mode open voltage???

[@keithking1985]

Good luck with the surgery Paul 😷👍

[@learnelectronics]

Surgery was successful. Already feeling better.

[@keithking1985]

@@learnelectronics that's great news very happy to here that💃😆

[@MassimoTava]

Maybe you can take the camera to the hospital. Lots of interesting medical equipment

[@camurgo]

lol! That would be something, him reviewing the medical machines while being a patient.

[@pulesjet]

Wish they made the fuses accessible via battery compartment.

[@geirendre]

Nice meter, can see why you like it, but at that price it should be good. But I'm not into the reverse display idea, don't see the reason (use) for it. Best of luck with your surgery, and a good recovery.

[@Brian-uq6jm]

Totally agree, backlight being always on drains battery like crazy. And it doesn't really offer much other than looking different from most multimeter displays.

[@insoft_uk]

A UNI-T your main meter, I’m surprised would of thought you have a FLUKE or some other high quality meter. Not that I’m saying UNI-T is a bad meter as I use them as I don’t have a lot of money to afford one of the higher accuracy meters just surprised with all the stuff you have you picked UNI-T

[@3rdpig]

Interesting. It seems like it's aimed at A/C techs. But why make a meter for them that has a screen that's probably unreadable in direct sunlight? Show me that same meter, with bluetooth or data logging, but with a regular LCD, price it under $100 and I'd probably order one right now...or as soon as I saw your review.

[@learnelectronics]

Check out the owon 18B then

[@camurgo]

It seem this meter has great protection circuits, I'm surprised.

[@percyv.morales2583]

Frecuency dc ?

[@saeedhassan7927]

get well n thanks for the content

[@mtkoslowski]

I wish you all the best.

[@bblod4896]

Nice. Only proves the point, you get what you pay for. Hope all works out on Friday.

[@docs3391]

I got the same one. Very good DMM.

[@kaybhee6]

thanks boss... getting the e

[@Irich1961]

Get well soon matey.. :o)

[@pda49184]

Great review and critique Paul.. Think I might get one of those.. You can''t have too many DMM's.. Best wishes for Friday & see you when it's all done & dusted..

[@dwpetty3723]

Don't like that blue display

[@alfistialfisti1072]

139C FUN CLUB

[@zxrjimmy1]

Just stick with fluke, brymen, keysight

[@learnelectronics]

My videos of for folks just getting started. I'm happy you like your very expensive meters but not everyone needs or can afford them. I'm just show that there are alternatives.

[@user-cm1od3dz3m]

Антиреклама в действии. Более отвратительного дисплея я не видел!

[@tanishqbhaiji103]

Not good enough

[@marceloandrade225]

Another multimeter review..... it is getting boring.
